Of course, I understand you might need them, but then the change does
not belong to this patch. Actually you've done that correctly for the
spinand_wait() helper.

You can do all the "make foo() global" operations in a single patch if
you want.

I will soon review more in deep the content of this patchset again.

Thanks,
Miquèl
